免费在线 OCR 程序与商业程序相比如何?
与在线免费提供的软件相比,商业 OCR 软件要好多少? 更具体地说:阅读图片中的文字(例如书籍封面等......)
How much better would commercial OCR software be compared to the stuff that's available online for free?
More specifically: Reading text in pictures (things like book covers etc...)

我经常使用 OCR 进行工作,并且绝对可以保证商业产品比您可以免费找到的要好得多。是的,您可以让免费的“工作”,但这需要付出很大的努力才能获得次优的结果。
我建议寻找使用 ABBYY FineReader 的产品:它只需很少的配置即可完成出色的工作。
您可能需要考虑是否需要使用 OCR 供应商或最终用户应用程序提供的 SDK。 SDK 将提供其所发现内容的位置详细信息等,并提供更深入的控制,但价格会更高。最终用户包基本上只会读取它找到的所有内容,但是您可以将其设置为自动或基本控制它,并且它可能足以满足您想要做的事情,并且可能便宜得多。
获取试用版并尝试一下!
I work with OCR quite a lot and can definitely vouch that the commercial offerings are much better than what you can find out there for free. Yes, you can make a free one 'work', but it will take a lot of effort for sub-optimal results.
I recommend finding a product that uses the ABBYY FineReader : It does a great job with little configuration.
You may want to consider whether you need to use an SDK provided by the OCR supplier or an end-user application. The SDK will provide position details, etc of what it finds and offer a lot more in-depth control, but will be more expensive. The end-user package will basically just read everything it finds, but you may be able to set it to automatic or control it rudimentally and it might be good enough for what you're trying to do, and may be a lot cheaper.
Get a trial version and give it a go!
